| Abstract Scope |
Recent advances in additive manufacturing have enabled high-volume, low-cost production of multiscale architectured porous wicks for loop heat pipes. Wicks developed through additive manufacturing, however, have low permeability, limiting thermal performance. We develop a physics-informed design approach for additively manufactured loop heat pipe wicks, aiming to maximize the rate of surface evaporation, compensating for other shortcomings in the additive manufacturing process. Using our multiscale architectured porous wicks, we find a 50% improvement in thermal performance over other state-of-the-art designs. Additionally, we demonstrate a 2-week design-manufacturing-test lead time and less than 3% performance variation across several manufactured samples. In addition to our design methodology and process, we present the motivation for low-cost manufacturing of loop heat pipes and future avenues for development in multiscale porous architectured materials. |
